I can't imagine a better biography of C S Lewis. George Sayer was a pupil of Lewis at Oxford and came to be one of the author's best friends. Over the years Mr Sayer even became a sort of advisor to Lewis and assisted him through his illness is later years as well as estate matters.

George Sayer, also a professor, came to know Lewis's friends such as J R R Tolkien and others. He Researched and fully describes his childhood, his brother Warren's childhood and subsequent alcoholism, and everything about the man including his sex life and/or lack of one.
Mr Sayer knew Joy Davidman Gresham and describes her moods and demeanor to a tee.

Anyone who admires the work of C S Lewis will be interested to know that he did not have the comfortable life of a successful writer. God gave Lewis, as He does with most Christians, many challenges that only faith can overcome. Nevertheless, C S Lewis kept his sense of humor and his love of life and nature until the very end.

George Sayer holds nothing back in this biography. He shows his love and admiration for his friend Lewis, but also gives insight to his faults and weaknesses.
